Quality

Fibres knitted into an ultra soft, breathable and moisture absorbing fabric that is uniquely soft as well as environmentally friendly. We combine and quilt this with Australian Hypersoft foam to virtually eliminate body impressions and increase airflow through the mattress.

Ocean-friendly fabric

Super soft. Super sustainable.

Every Atlantis mattress features a knitted and quilted top cover that combines Seaqual YarnⓇ , made from discarded marine plastic, with renewable Tencel, produced from certified sourced natural raw wood. These fibres are knitted into an ultra soft, breathable and moisture-absorbing fabric, and quilted with Australian Hypersoft foam to virtually eliminate body impressions and increase airflow through the mattress. So you can help save the planet while you sleep.

Ultra-breathable layers

Designed for maximum comfort.

Our tri-layered, pressure-relieving comfort layer system is designed to give you the perfect night’s sleep. Made in Australia from GECA-certified materials, our foams are high quality, durable and above all comfortable. And because we’ve designed it to allow maximum airflow and breathability, you’ll always find your mattress is the perfect temperature. Time to hit the snooze button.

Multi-zone contouring

Support in all the right places.

Thanks to our premium pocket spring, multi-zone support system, you’ll always feel support wherever you need it the most (as well as less disturbance if your partner’s a restless sleeper). And because the edge of your mattress features a firmer spring, there’s even more room to comfortably spread out. Which is great news for you - and whoever you’re sharing your bed with.

Introducing our 3 step comfort adjust process

01
Select your feel

Choose your ideal comfort level at purchase: firm, medium or soft. If you and your partner can’t agree, you can opt for a split feel that gives you the best of both worlds.

02
Sleep on it

Once your mattress has been delivered, we’ll give you three weeks to see if you’re happy with how it feels (it can sometimes take a bit of time to get used to a new mattress, hence the wait).

03
Change it up

Not 100% happy with the feel of your mattress? Change it for a different firmness level, free of charge. Your comfort layer can be easily swapped out at home by simply unzipping the mattress cover.

What people are saying

Our mattresses don’t come in a box, but they do tick every box. Don’t believe us? Read on.

Highly recommend.

Always had issues with back pain and my physio suggested I get a new mattress. Purchased a firm mattress from Atlantis three months ago and my back has really improved.
